Single server or multiple? <br />
Have you indentified where the SMTP traffic is going? <br />
<br />
If something was amiss (ie server being abused) then it would show in the logs. Fairly constant SMTP traffic isn't unusual, as spammers are always probing away at systems. <br />

We have a local &quot;office&quot; server which runs Exchange Server, we also have a Web Server that provides mail server services to our clients - we also use this. The local Exchange server gets emails from the Web / Mail server via the POP3 connector. Outgoing mails go directly (I think!!).<br />
<br />
Are there tools available to examine what the SMTP service is doing?

We have a Windows Server 2003 running Exchange Server - it is configured to use the POP3 connector (every 15 minutes) to retrieve emails from a remote server.<br />
<br />
I have noticed that there appears to be a constant stream of data being sent across the LAN (?), which stops as soon as I stop the SMTP service.<br />
<br />
I have never noticed this before - is it normal behaviour or could something &quot;bad&quot; be going on?
